The EV Road Trip Charging Kit: Every Adapter Worth Packing
During the NACS transition, packing both Tesla-to-J1772 and J1772-to-NACS adapters is cheap insurance — here's the full road-trip charging checklist.

Adapters are the unglamorous part of EV road-trip prep, and they're also the part that determines whether you can actually charge when you get somewhere unexpected. With the industry mid-transition to Tesla's NACS connector as the emerging standard, most EV owners — Tesla and non-Tesla alike — are currently living through a crossover moment where carrying the right adapters matters more than it will in a few years.
Why this crossover moment matters right now
For years, J1772 was the default Level 2 connector for non-Tesla EVs in North America, while Tesla used its own proprietary connector (now called NACS). That's changing: many automakers have committed to NACS, and Tesla has opened parts of its Supercharger network to non-Tesla vehicles via adapters. In practice, that means:
No spam. Unsubscribe anytime.
- Non-Tesla EV owners may need a Tesla-to-J1772 adapter to use certain Tesla-brand equipment, or a J1772-to-NACS adapter to access newer NACS-only stations with an older J1772 charge port.
- Tesla owners road-tripping through areas with mostly J1772 public Level 2 stations need the reverse adapter to plug into them.
Until the transition fully settles, packing both directions of adapter is cheap insurance against pulling up to a charger you can't physically connect to.
The checklist
- Tesla-to-J1772 adapter — lets a Tesla plug into standard J1772 Level 2 stations (the majority of non-Tesla public chargers today).
- J1772-to-NACS adapter — lets a J1772-equipped (non-Tesla) EV plug into NACS connectors, including many Tesla-brand chargers.
- A portable Level 2 charger with a NEMA 14-50 plug — for overnight charging at a relative's house or an RV park pedestal. See our portable Level 2 charger comparison for amperage and cable-length tradeoffs.
- Your vehicle's mobile connector / OEM charge cable — the cable that came with your car, even if you plan to rely on adapters and public stations most of the trip.
- A written note of your car's max onboard AC charge rate — knowing whether your car tops out at 32A, 40A, or 48A tells you whether a higher-amperage charger is worth carrying versus overkill.
- A backup plan for dryer/range outlets — many homes without a dedicated EV circuit still have a NEMA 14-50 range outlet. Read can you charge from a dryer outlet before you assume it'll work.
Two adapters, two directions
The Lectron Tesla-to-J1772 adapter is built for Tesla owners who need to charge at the far more numerous J1772 stations:
The LENZ J1772-to-NACS adapter covers the opposite direction — a J1772-equipped car plugging into a NACS-only or Tesla-brand charger:
For home base charging
If your road trip starts and ends at home and you're setting up a dedicated charger for both departure and return top-offs, the Tesla Universal Wall Connector is worth a look since it accepts both NACS and J1772 vehicles on the same unit — useful if your household has (or might eventually have) more than one EV brand:
The bottom line
Pack both adapter directions — Tesla-to-J1772 and J1772-to-NACS — regardless of which side of the transition your car is on; the cost of carrying an adapter you don't end up needing is far lower than the cost of standing at a charger you can't plug into. Round out the kit with a NEMA 14-50-compatible portable charger and you're covered for nearly any outlet or public station you'll encounter mid-trip.
